I just started reading this book and I was wondering if the code for the components described in it is available on line anywhere. So far the book is quite interesting. It is not parochial in that even though the techniques are discussed in an Ada framework they are generally applicable. It is interesting to note that the taxonomy for software components described in the book allows for both managed and unmanaged components. This is relevant to the current GC discussion. Both GC'd and non GC'd components have their place. The important thing to discuss is the specification of the component and not its storage management policy. Of course, the storage management policy will have an impact on the specification. One would expect, however, that GC'd and non GC'd versions of the same components would have much in common. What I would like to see in this group is pointers to collections (in any language) of useful components (such as the ones described in Booch's book). I would also like to see discussions about the quality of such collections. So far, for a group about reusable code, there has been precious little code to reuse presented here. -- Jose Oglesby oglesby@multiflow.com Multiflow Computer or oglesby@mfci.uucp 31 Business Park Drive or ...!uunet!mfci!oglesby Branford CT 06405 (203)-488-6090

They are sold by Wizard Software, 835 S. Moore Street, Lakewood, CO; the charge is from $100 for a one-CPU educational license to $5000 for a commercial site license, or at least that's what the prices were in October 1988. > What I would like to see in this group is pointers to collections (in > any language) of useful components (such as the ones described in > Booch's book). There is a guidebook called Ada: Sources and Resources which is written by Karl Nyberg of Grebyn Corporation (karl@grebyn.com) which gives a comprehensive survey for Ada components; the address is Karl Nyberg, Grebyn Corporation, P.O. Box 1144, Vienna, VA, 22180. > I would also like to see discussions about the > quality of such collections.

If you want lots of reuseable code, try the Ada Software Repository; for the cost of postage, you can get a very full magtape (6250 bpi in Unix tar format, several mag tapes at lower densities or other formats) full of reuseable code. (You must supply the tapes...) I'm e-mailing you a description of the Ada Software Repository and how to access it, which I will be happy to send to anyone else who requests it via e-mail to wtwolfe@hubcap.clemson.edu.
